Connector having a housing with resilient locking pieces

Abstract

A waiting side housing (M) includes resilient locking pieces ( 15 ) and resilient contact pieces ( 18 ). Locks ( 16 ) of the resilient locking pieces ( 15 ) restrict a displacement of the waiting side housing (M) toward a complete holding position by being locked to a mounting hole (H) and are separated from the mounting hole (H) only by resilient deformation of the resilient locking pieces ( 15 ). Contact portions ( 19 ) of the resilient contact pieces ( 18 ) are in contact with the mounting hole (H) with the waiting side housing (M) located at a temporary holding position. If tapered surfaces ( 20 ) of the contact portions ( 19 ) are pressed by an edge part of the mounting hole (H), the resilient contact pieces ( 18 ) are resiliently deformed to separate the contact portions ( 19 ) from the mounting hole (H).

What is claimed is: 
     
       1. A connector, comprising:
 a waiting side housing to be mounted to penetrate through a mounting hole of a panel and displaceable in a displacing direction between a temporary holding position and a complete holding position; 
 a resilient locking piece formed on the waiting side housing; 
 a lock formed on the resilient locking piece and configured to restrict a displacement of the waiting side housing toward the complete holding position by being locked to an edge part of the mounting hole with the waiting side housing at the temporary holding position and separate from the edge part of the mounting hole (H) only by resilient deformation of the resilient locking piece; 
 a resilient contact piece formed on the waiting side housing; 
 a contact portion formed on the resilient contact piece and configured to be held in contact with the edge part of the mounting hole in the same direction as a displacing direction from the temporary holding position to the complete holding position with the waiting side housing located at the temporary holding position; 
 a tapered surface formed on the contact portion, oblique to the displacing direction of the waiting side housing and configured to resiliently deform the resilient contact piece in a direction to separate the contact portion from the edge part of the mounting hole by being pressed by the edge part of the mounting hole; 
 a fit-in side housing connectable to the waiting side housing; and 
 a lock releasing portion formed on the fit-in side housing and configured to deform the resilient locking piece when the fit-in side housing is connected to the waiting side housing. 
 
     
     
       2. The connector of  claim 1 , further comprising at least one pressing portion formed on the fit-in housing and capable of pressing the resilient locking piece in a direction to increase a locking margin of the lock with the edge part of the mounting hole in a state where the lock releasing portion is not interfering with the resilient locking piece. 
     
     
       3. The connector of  claim 2 , wherein a plurality of resilient locking pieces are arranged at positions point-symmetrical with respect to a virtual center axis parallel to a connecting direction of the waiting side housing and the fit-in side housing. 
     
     
       4. The connector of  claim 3 , wherein a plurality of resilient contact pieces are arranged at positions point-symmetrical with respect to a virtual center axis parallel to a connecting direction of the waiting side housing and the fit-in side housing.
